Corrections please.

Good job! Normally you don't capitalize words unless they are (1) the first word of a sentence or (2) the words in the title of a book or essay. Sometimes you see random words capitalized in poems or song lyrics, but they are breaking the rules to create a visual style. Hope this helps! :-)
